Service Bulletin – June 2023 SAF Tire Pilot Plus™ (TPP) Inflation System 1 Tire Pilot Plus Safety Concern Tire Pilot Plus (TPP) system produced on trailers after November 2022 with the electronic regulator assembly have been determined under specific conditions to slowly deflate the trailer tires. The following instructions provide the necessary information for identifying and disabling the Tire Pilot Plus system. It is required to disable the Tire Pilot Plus system until troubleshooting and root cause determination work is complete. Service repair kit SRK-951 (Part Number – 48100817) is available for this procedure and the parts within the kit are commercially available as shown below. The kit includes nine 1/4 NPT pipe plugs and eight valve stem caps. Tire Pilot Plus Inspection and Disable Process INSPECTION: 1. Check the trailer build date on the VIN tag. If it was manufactured November 2022 or later, the trailer could be in the target group, but needs to be confirmed to have the electronic regulator assembly installed. 2. Figure 1 illustrates the new electronic regulator that will need to be disabled. Location is on the front crossmember for a sliding suspension. 3. Before performing any maintenance on the trailer, set the parking brake and block the tires. Failure to set the parking brake and chock the tires prior to beginning maintenance could allow the vehicle movement which, if not avoided, could result in death or serious injury.

Loosen and remove the tire hoses by hand starting at the hubcap fitting (Figure 2). Tire hoses should be disposed. 3. Remove the tire hose fitting from the hubcap using a 15mm or 9/16″ deep well socket. (Figure 3). 4. Install a valve stem cap on the tire valve stem (Figure 4). 5. Install the 1/4 NPT pipe plug in the hubcaps. Install hand tight plus 2 turns or 25-30 lb-in (Figure 5). 6. Disconnect the air line from the PPV as illustrated (Figure 6).

Re-tighten the trai ler air tank drain. 10. Verify steps 2 through 9 are completed per instructions. NOTE: DO NOT disconnect the electrical connection to the electronic regulator. Open electrical connectors will corrode, collect contamination and cause performance issues when the system is re-activated. For this procedure SAF-HOLLAND will reimburse 1/2 hour of labor per trailer. Once the procedure is done, you will need to supply: „ trailer make „ trailer VIN „ trailer in-service date „ both axle serial numbers „ suspension serial number „ date of repair „ authorization number to SAF-HOLLAND warranty at service@safholland.com for labor reimbursement. If other warrantable issues are found during the disabling of the TPP electronic regulator, a separate claim must be filed for those items. We apologize for any inconvenience this may have caused.

Trailers equipped with Tire Pilot Plus – Electronic Regulator Control Unit Assembly tire pressure regulation system (TPRS) may experience unintended loss of pressure of all 8 tires while traveling at speeds higher than 45 mph. This loss of pressure event occurs only on the Tire Pilot Plus – Electronic Regulator Control Unit Assembly that was launched by SAP-HOLLAND in late 2022. As a result of the above, SAP-HOLLAND has decided to voluntarily initiate a Safety Recall campaign of the TPP Systems that may be affected by the issue. The safety defect has been reported to NHTSA and we are in the process of taking the required steps to implement a safety recall of Tire Pilot Plus – Electronic Regulator Control Unit Assembly tire pressure regulation system (TPRS). What The Issue Is: Tire Pilot Plus product equipped with Electronic Regulator Control Unit Assembly tire pressure regulation system sold by SAP-HOLLAND that utilize an electronic tire pressure control module. What SAP-HOLLAND Will Do for you: 1. SAP-HOLLAND is currently developing a permanent remedy for this issue. 2. In the meantime, as an interim step we require that fleets operating trailers equipped with effected TPP systems disable the system and for fleets to manage tire pressure manually.

Production Dates : DEC 01, 2022 – JUN 15, 2023 Description of Defect : Description of the Defect : Some trailers equipped with SAF-HOLLAND suspension systems equipped with Tire Pilot Plus – Electronic Regulator Control Unit Assembly tire pressure regulation system (TPRS) are experiencing unintended loss of pressure of all 8 tires while traveling at speeds higher than 45 mph. This loss of pressure event occurs only on suspension systems equipped with the Tire Pilot Plus – Electronic Regulator Control Unit Assembly that was launched by SAFHOLLAND in late 2022. FMVSS 1 : NR FMVSS 2 : NR Description of the Safety Risk : Reduced vehicle control and/or stability that could result in a crash. Risk of tire tread separation and debris on the road.

Description of Remedy : Description of Remedy Program : The interim corrective action is to disable the TPP system on the CBXA40 and ULX40 Suspension Systems and for fleets to manage tire pressure manually. The final corrective action will not be known until the root cause has been determined. SAF-HOLLAND will pay appropriate costs. How Remedy Component Differs from Recalled Component : The Interim corrective action will result in disconnected air supply hoses on all tires and at the ECU.
